Numerous problems with postfix's newaliases.

[Aleksey Nogin]

When MTA is set to postfix, if I try to use newaliases in enforcing 
mode, I get:

audit(1083135148.926:0): security_compute_sid:  invalid context 
root:system_r:sysadm_mail_t for scontext=root:sysadm_r:sysadm_mail_t 
tcontext=system_u:object_r:postfix_master_exec_t tclass=process

and execution fails.

In permissive mode, I see:
